Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Socket set and wrench set: Various sizes will be needed.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Ball joint separator: To separate the ball joint from the knuckle.
* Tie rod end separator: To separate the tie rod end from the knuckle.
* Hammer and punch: May be needed for stubborn parts.
* Press or bearing puller: To remove the old bearing from the hub.
* New front wheel bearing hub assembly: Make sure you get the correct part number for your specific vehicle.
* Grease: For packing the new bearing.
* Penetrating lubricant (PB Blaster, etc.): To help loosen rusted or seized parts.
* Safety glasses and gloves: Always protect yourself.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park the vehicle on a level surface, engage the parking brake, and chock the rear wheels. Wear safety glasses and gloves.
2. Disconnect the Battery: Disconnect the negative (-) battery terminal to prevent electrical shorts.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Disconnect Brake Caliper: Remove the brake caliper and hang it securely out of the way using a wire or bungee cord. Do *not* let the brake hose hang freely.
5. Disconnect ABS Sensor (if applicable): Carefully disconnect the ABS sensor wire from the hub.
6. Disconnect Tie Rod End: Use a tie rod end separator to separate the tie rod end from the steering knuckle. Mark the position of the tie rod end before disconnecting it to ensure correct alignment later.
7. Disconnect Ball Joint: Use a ball joint separator to separate the lower ball joint from the steering knuckle. This may require significant force.
8. Remove the Knuckle: After disconnecting the tie rod and ball joint, the knuckle should be able to be removed. This step can vary widely based on the specific design.
9. Remove the Old Hub Assembly: This usually involves removing cotter pins, nuts, and potentially using a press or bearing puller to remove the old hub assembly from the knuckle.
10. Install the New Hub Assembly: Pack the new hub assembly with grease according to the manufacturer's instructions. Install the new hub assembly onto the knuckle, ensuring proper alignment.
11. Reassemble Everything: Reinstall the knuckle, ensuring the ball joint and tie rod end are properly connected. Reconnect the brake caliper, ABS sensor, and wheel.
12. Torque Specifications: Tighten all bolts and nuts to the manufacturer's specified torque values using a torque wrench. This is crucial for safety and proper function.
13. Lower the Vehicle and Test: Carefully lower the vehicle and test the steering and braking. Check for any unusual noises or vibrations.
Important Considerations:
* Wheel Alignment: After replacing the hub assembly, you'll almost certainly need a wheel alignment. Improper alignment can lead to tire wear and handling problems.
* Parts: Make sure you obtain the correct parts for your specific vehicle. Using the wrong parts can lead to failure and safety hazards.
* Repair Manual: A repair manual specific to your 1996 Suburban K2500 is invaluable. It will provide detailed instructions, torque specifications, and diagrams.
This is a complex repair. If you are not comfortable performing this repair yourself, it's strongly recommended to take your vehicle to a qualified mechanic. Attempting this repair without the proper knowledge and tools could lead to damage to your vehicle or injury to yourself.
